"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

"We sold our home and we needed a waterproofing expert to come out and inspect some basement cracks for water leaks. We needed this done pretty quickly and other companies we had contacted were all booked up. I got in touch with this company and Marty gave me a call back and offered to come by in the evening after he was done with his last job of the day to take a look at this for us. Right then I knew we had picked the right company. As a business owner, I really appreciated him going this extra mile. Marty didn't have an opening until the following week but knowing we needed this done pretty quickly he got there to inspect our basement quickly. He was very knowledgeable and just a great guy! We would definitely recommend Marty and this company for any of your basement waterproofing needs!"

"I had a big name waterproofing company out several years ago that did work on two walls of my house and continued to have problems with leaking. They did come back a few times and tried to repair but never could get it sealed properly. After paying a annual fee to keep a warranty for a problem they couldn't repair I decided to get a few contractors out and look to get another opionon. Buckeye Waterproofing was by far the most experienced of them and explained everything that was going on so I and my son-in-law could understand and make sense. They told me what was needed to be done to repair what previous company did and what would be needed for the rest of the house. After sitting with Rick from Buckeye I had decided to have them do the work because he made me feel so comfortable with the work he would be doing and gave me the best price of the quotes we had. Everyone else wanted to do start from scratch and do previous work I had done over while Rick explained he could repair the work and save me some money since I had already paid for work years ago. The crew Rick sent was prompt,clean and very respectful of my house and I was extremely satisfied with work they did. It has now been 2 months since the work was done and everything has been dry with no issues at all on the new work that was done or the repairs to the old work that the other waterproofing company did and couldn't figure out how to repair. I would highly recommend this company to anyone and have already sent them a friend to have work done as well.

Basement Waterproofing FAQs, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.
